Abstract

Homogeneous Charge Compression Ignition (HCCI) is an advanced combustion technology being considered for internal combustion (IC) engines. In principle, HCCI involves the auto-ignition of a homogeneous mixture of fuel, air and diluents at low to moderate temperatures and high pressure. This approach enables the engine designer to have a high compression ratio, minimize air throttling losses, and radpidly burn the fuel-air mixture, which contributes to high fuel-conversion efficiency. Meanwhile, the burning of homogenenous fuel-lean mixture at relatively low temperature suppresses the formation of PM and NOx, which are the two problematic emissions from diesel engines. These desirable combustion characteristics make HCCI a potential alternative combustion mode to traditional IC engines.
